This document provides guidance on how to configure the BIG-IP LTM to optimize connections from SharePoint 200 servers to a FAST Search Server 200 farm. FAST Search Server 200 for SharePoint uses deep linguistics and text analytics technology to add tags and structure to unstructured information, automatically creating metadata directly from the content. For more information on, see For more information on the BIG-IP LTM, see For other deployment guides on configuring F5 devices with Microsoft SharePoint, see: Products and versions tested Product Version BIG-IP LTM 0.2., 0.2.2, SharePoint FAST Search Server 200 Prerequisites and configuration notes The following are general prerequisites and configuration notes for this guide: h h You must already have a working FAST Search for SharePoint 200 deployment, and that you are using the default port numbers for each FAST service. h h If you are configuring the BIG-IP LTM as described in Configuring a local virtual server for SharePoint 200 on page 9 to ensure thumbnails are properly displayed in FAST search results, the virtual server you create must be on the same VLAN as the FAST Search servers; this section is written with the assumption that the SharePoint 200 servers are also on this VLAN.

2 h h Because SharePoint 200 uses built-in load balancing to communicate with the FAST Search farm, you need to specify the IP address and service port of the BIG-IP LTM virtual server instead of individual server FQDNs when configuring the FAST Query SSA properties. This setting is found in SharePoint Central Administration>Application Management>Service Applications. Consult the Microsoft documentation for configuring FAST Search for more information. h h If you want to encrypt communication between SharePoint 200 and the FAST Search Query service, follow the instructions from Microsoft for enabling SSL on the FAST Search servers and in the properties of the SharePoint 200 Query SSA. Because FAST Search does not support SSL offloading, you will also need to apply a server SSL profile to the Query virtual server as described in this guide. h h You are NOT required to create all of the virtual servers described in this guide; you can choose to deploy any combination of them depending on how many FAST servers are running each role (for example, you may have only one server running FAST Admin service). Important h h When using the BIG-IP LTM system for SSL offload, for each SharePoint Web Application that will be deployed behind LTM, you must configure your SharePoint Alternate Access Mappings and Zones allow users to access non-ssl sites through the SSL virtual server and ensure correct rewriting of SharePoint site links. See Configuring SharePoint Alternate Access Mappings to support SSL offload on page 3 Configuration example The following diagram shows the traffic flow for the configuration described in this guide. Clients 3 BIG-IP LTM SharePoint 200 Servers 6 SharePoint FAST Search Server 200 farm. The user makes a request to the SharePoint server. 2. The external BIG-IP LTM virtual server receives the request and directs the user to an available SharePoint server. 3. If split DNS is not configured, and requests from the SharePoint 200 front end servers to the SharePoint URL are routed through the external SharePoint virtual server on the BIG-IP LTM, users may experience missing thumbnails in FAST Search results when a request from the WFE server is load balanced to another server rather than to itself. To prevent this, we create a virtual server on the SharePoint server VLAN and the irule in #5. 2

3 4. The Host entry on the SharePoint server points to the internal virtual server on the BIG-IP LTM. The SharePoint SSA is configured to use the BIG-IP LTM virtual servers for FAST search. 5. A BIG-IP virtual server on the same local VLAN as the SharePoint 200 servers includes an irule that ensures each request is directed to the same server that made it, so thumbnails are properly displayed. 6. The search request travels from the SharePoint servers to the FAST virtual servers on the LTM. 7. The BIG-IP LTM directs the request to the appropriate FAST server. Configuring SharePoint Alternate Access Mappings to support SSL offload When using the BIG-IP LTM system for SSL offload, for each SharePoint Web Application that will be deployed behind LTM, you must configure your SharePoint Alternate Access Mappings and Zones allow users to access non-ssl sites through the BIG-IP LTM SSL virtual server and ensure correct rewriting of SharePoint site links. For SSL offload, the Alternate Access Mapping entries must have URLs defined as where FQDN is the name associated in DNS with the appropriate Virtual Server, and assigned to the SSL certificate within the Client SSL profile. For each public URL to be deployed behind LTM, you must first modify the URL protocol of the internal URL associated with that URL and zone from to and then recreate the URL. If you try to just add a new URL for HTTPS, it will not function properly. For more information, see To configure SharePoint Alternate Access Mappings. From SharePoint Central Administration navigation pane, click Application Management. 2. In the main pane, under Web Applications, click Configure alternate access mappings. 3. From the Internal URL list, click the Internal URL corresponding to the Public URL you want to be accessible through the BIG-IP LTM. The Edit Internal URLs page opens. 4. In the URL protocol, host and port box, change the protocol from to You may want to make note of the URL for use in step Click the OK button. You return to the Alternate Access Mappings page. 6. On the Menu bar, click Add Internal URLs. 7. In the URL protocol, host and port box, type the same internal URL used in step 4, but use the protocol. This allows access to the non-ssl site from behind the LTM. 3

4 8. Click Save. You must also add the new internal URL(s) to the list of Content Sources of Search Administration. 9. From the navigation pane, click Application Management, and then under Service Applications, click Manage service applications. 0. Click the name of your Search Service application. In our example, we are using Microsoft Fast Search Server, so the following examples are based on Fast Search Server.. In the navigation pane, click Content Sources. 2. On the Menu bar, click New Content Source. 3. In the box, type a name. We type 4. In the Start Addresses section, type the appropriate HTTPS URL. In our example, we type All other settings are optional. 5. Click the OK button. 6. Repeat this entire procedure for each public URL to be deployed behind LTM. Displaying HTTPS SharePoint Search Results After Configuring Alternate Access Mappings for SSL Offloading After configuring Alternate Access Mappings in SharePoint 200 to support SSL offloading, you must perform additional steps to ensure that search results are properly displayed for queries. The examples below depict modifying the Content Search Service Application; however, you must also perform these steps on your Query Search Service Application. To ensure HTTPS search results are displayed. From SharePoint Central Administration navigation pane, click Application Management. 2. Under Service Applications, click Manage service applications. 3. From the Service Application list, click your Content SSA. If you are using the default content 4

5 SSA, this is Regular Search. If you are using FAST Search, this is the name you gave the content SSA (such as FAST Content SSA). 4. From the navigation pane, under Crawling, click Index Reset 5. Click the Reset Now button to reset all crawled content. The next three steps are performed on the FAST servers. 6. Log into one of the FAST servers and open the FAST Search Server SharePoint PowerShell console. 7. From a prompt, run the following command against the content collection for which you are resetting the index: Clear-FASTSearchContentCollection 8. Type Y to confirm. You can exit the command prompt. 9. Return to your Content SSA (repeat steps -3). 0. From the navigation pane, under Crawling, click Content Sources.. Click the content source for which you just reset the search index. 2. From the Edit Content Source page, in the Start Full Crawl section, check the Start full crawl of this content source box and then click the OK button. When the crawl is complete, users should receive addresses in their search query results. 5

6 Configuring the BIG-IP LTM for FAST Search Server 200 Use the following tables to configure the BIG-IP LTM system. The tables contain a list of BIG-IP LTM configuration objects, along with any non-default settings. Unless otherwise specified, settings not mentioned in the table can be configured as applicable for your configuration. For specific instructions on configuring individual objects, see the online help or product manuals. As mentioned in the prerequisites, you are not required to create all virtual servers listed in the table, depending on your configuration.

9 Configuring a local virtual server for SharePoint 200 If you are not using split DNS, and requests from the SharePoint 200 front end servers to the SharePoint URL are routed through the external SharePoint virtual server on the BIG-IP LTM you may see problems with missing thumbnails in FAST Search results when a request from the WFE server is load balanced to another server rather than to itself. In this case, you need to configure a virtual server on the same local VLAN as the SharePoint 200 servers that includes an irule. The irule ensures each request is directed to the same server that made it. You must also add a host entry to the WFE servers directing all requests for the SharePoint URL to the IP address of the internal SharePoint virtual server. See the Microsoft documentation for instructions. Use the following table to create the objects on the BIG-IP LTM. Unless otherwise specified, settings not mentioned in the table can be configured as applicable for your configuration. For specific instructions on configuring individual objects, see the online help or product manuals.
